Subject: [PATCH] ia64: Fix iosapic interrupt delivery mode for CPE
Date: Fri, 09 Nov 2007 01:51:01 +0000 [thread overview]
Message-ID: <4733BD05.8040804@jp.fujitsu.com> (raw)
If "CPEI Processor Override" bit is not set in "Platform Interrupt
Source Flags" in "Platform Interrupt Sources Structure" in ACPI MADT,
the target processor of CPEI is restricted to a specific CPU. Because
of this, the delivery mode for CPEI should be IOSAPIC_FIXED.
